` 'lllhis invention relates to terminal puller-s for removing the terminals of storage batteries.

lln important object of the invention is to provide a unitary tool embodying plier-connected jaw implements, which may be used to withdraw a terminal where the same is badly corroded or too firmly engaged with the terminal post and a pressure bar to be l@ employed with the jaw implement in event it is found that an ordinary pull will not re- -move the terminal..

di further object of the invention is the provision of a structure such that these elelo ments may be readily and conveniently combined.

rllhese and other objects l attain by the construction shown in the accompanying drawings, wherein for the purpose of illus- E@ tration is shown a preferred embodiment of my invention and wherein lligure l is a side'elevation of `a terminal puller constructed in accordance with my invention;

llligure 2 is an edge elevation thereof. liteferring now more particularly to the drawings, the numerals l0 and ll indicate plier-connected members, each having one end in the form of a jaw l2 and the other 3@ end in the form of a handle 13. Said elements at the decussation thereof are widened and furcated, one of the elements being directed through the furcation lll of the other. .ll pivot Il is passed through this decussation and will, of course, be exposed at the furcation ltl of the first named element. The enposedl portion of the pivot has formed therethrough a vertical bore ll through which is directed a plunger l@ having at its upper end and between the handle sections ld a head i9.v lflivoted to one of the handle sections is a bell cranli lever having a short arm 2O and a long arm 2l. 'lhe short arm has an angular portion provided with a cam face 22 overlying the head lll, while the upper end of the long arm is formed as a handle 23. 'lhe jaws l2 are provided with o posed engaging danges 2d, the extremities of which are sharpened and the upper faces of which are preferably straight and perpendicular to the jaws, as indicated at 25.

lin the use of the tool, the handles l?) are grasped to force the engaging flanges 24e into the terminal. lUnder most circumstances, a pull upon these handles, after the flanges are properly engaged in the terminal,

will suffice to remove the terminal. l'lhen the terminal is stubborn, after the Hanges have been engaged therein, the handle 23 and the handle 13 of the plier member lll are engaged with the hands. 'llhis operation tends to force the plunger l@ downwardly and at the same time to force the jaws l2 toward one another, with the result that the grip upon the terminal is maintained and a considerable pressure exercised against the post to force the terminal theren from.

llt will be obvious 'that such a structure may be very conveniently manipulated and may be relatively cheaply produced. ldince the construction hereinbefore set forth is capable of a certain range of change and modification Without materially departing from the spirit of the invention, l do not limit myself to such specific structure err` cept as hereinafter claimed.

l claim l. lln a battery terminal puller, a pair of plier-connected elements including jaws for engagement with the terminal and a plunger for simultaneously engaging a post upon which the terminal is mounted, and means engageable simultaneously with the handle of one of the plier-connected elements for forcing the handle of the other of the plierconnected elements toward the first named handle and for shifting said plunger longitudinally tov exert pressure upon the ternainal.

2. ln a battery terminal puller, decussate elements pivoted at the decussation and each formed at one end with a jaw and at its o posite end with a handle, a plunger slida ly directed through the pivot to move in the general direction of the airis of an element disposed between and engaged by said jaws, and means engageable simultaneously with the handle of one of said elements for forcing the handle of the other of the elements toward the first named handle and for shifting said plunger longitudinally.

3. ln a battery terminal puller, decussate elements pivoted at the, decussation and each form-ed at one end with a jaw and at its opposite end with a handle, a plunger' slidably directed through the pivot to move in the general direction of the airis of an element disposed between and engaged by said jaws, and a lever pivoted to the handle of one of said elements and having at one end a handle extending upwardly between the handles of lill the'elements, the op osite end of the lever means for simultaneously shiftin said jaws being in the form o a cam engaging said toward one another and shi ting said plunger. v plunger longitudinally. 10 4. n a battery terminal puller, a air of In testimony whereof I hereunto aix my 5 jaws for engagement with a termina and a signature.
